Seems relevant for this list :) Haven't looked close at it yet - Sent from my tablet <div class="gmail_quote">---------- Vidarebefordrat meddelande ---------- Från: "Dmitri Vitaliev" <<a href="mailto:dmitri@equalit.ie">dmitri@equalit.ie</a>> Datum: 10 dec 2014 17:31 Ämne: [liberationtech] (n+1)sec = more privacy on the internet Till: <<a href="mailto:liberationtech@lists.stanford.edu">liberationtech@lists.stanford.edu</a>> Kopia: <div bgcolor="#FFFFFF" text="#000000"> Dear Libtech In recognition and celebration of Human Rights Day, eQualit.ie is proud to release the first public draft of a provably secure protocol for group messaging on the Internet <a href="https://learn.equalit.ie/wiki/Np1sec" target="_blank">https://learn.equalit.ie/wiki/Np1sec</a> The protocol provides for end-to-end security of synchronous communications between any number of people. It is efficient and builds on recent advancements in cryptographic research. Security properties of (n+1)sec include: * Confidentiality: the conversation is not readable to an outsider * Forward secrecy: conversation history remains unreadable to an outsider even if participants’ encryption keys are compromised * Deniable authentication: Nobody can prove your participation in a chat * Authorship: A message recipient can be assured of the sender’s authenticity even if other participants in the room try to impersonate the sender * Room consistency: Group chat participants are confident that they are in the same room * Transcript consistency: Group chat participants are confident that they are seeing the same sequence of messages The protocol is being implemented as a FLOSS libpurple plugin and will find its first home in <a href="http://crypto.cat" target="_blank">crypto.cat</a>. We anticipate wide adoption in other instant messaging platforms.
